MatSetValuesRowLocal#
Inserts a row (block row for MATBAIJ matrices) of nonzero values into a matrix
Synopsis#
#include "petscmat.h"
PetscErrorCode MatSetValuesRowLocal(Mat mat, PetscInt row, const PetscScalar v[])
Not Collective
Input Parameters#
mat - the matrix
row - the (block) row to set
v - a logically two-dimensional array of values
Notes#
The values, v, are column-oriented (for the block version) and sorted
All the nonzero values in row must be provided
The matrix must have previously had its column indices set, likely by having been assembled.
row must belong to this MPI process
